Plant fertilizers are categorized by the percentage of nitrogen (N), phosphorous (P), and potassium (K) they contain, by weight. For example, a fertilizer that has N-P-K numbers of 8-5-5 has 8% nitrogen, 5% phosphorous, and 5% potassium by weight. Suppose that a fertilizer has four times as much potassium by
weight as phosphorous. The percentage of nitrogen equals the sum of percentages of phosphorous and potassium. If nitrogen, phosphorous, and potassium
make up 30% of the fertilizer, determine the proper N-P-K label on the fertilizer
